The **ACE1V4532-101-R** is a specific electronic component belonging to the category of **Common Mode Chokes** (Common Mode Filters). These are primarily used for EMI (Electromagnetic Interference) suppression in high-speed signal lines. --- ## 1. Technical Specifications Below is a breakdown of the key parameters for this specific part number: | Parameter | Specification | | :--- | :--- | | **Component Type** | Common Mode Choke | | **Inductance** | 100 $\mu$H (at 100 kHz) | | **Tolerance** | -30% / +50% | | **DC Resistance (DCR)** | 2.0 $\Omega$ (Max) | | **Rated Current** | 150 mA | | **Rated Voltage** | 50 V | | **Insulation Resistance** | 10 M$\Omega$ (Min) | | **Operating Temperature** | -40°C to +125°C | --- ## 2. Part Number Breakdown The naming convention follows the manufacturer’s (likely **Pulse Electronics** or a compatible brand) standard logic: * **ACE1V**: Series identifier for Automotive Grade Common Mode Chokes. * **4532**: Package Size. This refers to the metric dimensions: **4.5mm x 3.2mm** (Equivalent to EIA 1812). * **101**: Inductance Code. The first two digits are significant figures, and the third is the multiplier ($10 \times 10^1 = 100 \mu\text{H}$). * **R**: Typically denotes RoHS compliance and Reel packaging. --- ## 3. Core Functions and Applications This component is designed to filter out "noise" that is common to both lines of a differential pair while allowing the actual signal to pass through. ### Key Applications * **CAN-Bus / FlexRay:** Essential for automotive communication protocols to ensure data integrity in noisy engine environments. * **Ethernet Lines:** Used in telecommunications to reduce electromagnetic radiation. * **DC Power Lines:** Filtering high-frequency ripples in small power circuits. ### Features 1. **AEC-Q200 Qualified:** This means the part is tested for high reliability in automotive environments (vibration, heat, and humidity). 2. **Surface Mount (SMD):** Designed for automated pick-and-place assembly. 3. **High Impedance:** Provides high suppression for common-mode noise across a wide frequency range. --- ## 4.
